I bought a ton of Wolf primers when it seemed thats all I could get a few months back.. Now I'm finally reloading brass with used Wolf Primers. The weird thing is, every 500 rds or so that I load, about 10-15 have primers that wont come out. The decapping pin goes straight through the case basically pops the top off the primer, leaving the side walls in the case. It's become a pain in the ass with my 650 on the downstroke. Any ideas why this is happening? Thanks
